	On the tandem accelerator with vacuum insulation in a steady long mode it was obtained 1.6 mA current of protons with 2 MeV energy. It was studied the one of the possible reasons of current limitation – the appearance of accompanying charged particles during acceleration of the ion beam. The paper presents and discusses the results of the accompanying beam measurement using a special detector. The detector registered an opposite positive current in the range of 80-170 mkA, which is directly dependent on vacuum conditions in the accelerator. Also it was measured the dependence of the dose rate on the total current in the accelerating gap. These measurements confirmed that injected H⁻ beam ionizes residual and stripping gas mainly in the area before the first electrode and two proposals were made to minimize the accompanying current.

WEPSB18	Modification of the Argon Stripping Target of the Tandem Accelerator	ion, vacuum, proton, tandem-accelerator	194
	Y.M. Ostreinov, A.N. Makarov, S.Yu. Taskaev, P. Vobly BINP SB RAS, Novosibirsk, Russia
	The paper presents and discusses the project of modified gas stripping target. The idea of the target modification is the following. Inside the high-voltage electrode just behind inlet aperture it is proposed to apply 1 T transverse magnetic field using a two-pole permanent magnets. Similar magnets at the exit of the stripping target return proton beam back to the axis of accelerator channel. In this geometry not only significant suppression of ion penetration of the stripping gas into the accelerating channel can be achieved, but also a significant improvement of vacuum conditions in the accelerating channel and reduction of the ultraviolet radiation from the plasma in the stripping target. It is enough to shift the stripping target to a distance greater than the aperture (20 mm) in the high-voltage electrode and to implement a differential gas pumping. The paper presents results of trajectory calculation of the injected ion beam in Comsol Multiphysics. The geometry of the magnetic system and the system of differential gas pumping using turbomolecular pump installed inside the high-voltage electrode are presented.

	In the present work the installation created on the basis of the accelerator EG-1 (IPPE) for the experimental studies of the time dependence of delayed neutron activity from neutron induced fission of 235U is described. Measurements were carried out with neutron beam generated with the help of the 7Li(p, n) reaction. The lower limit of the investigated time range was governed by the proton beam switching system that was 20 ms. It was shown that the temporary characteristics of delayed neutrons from the fission of 235U by epithermal neutrons is consistent with the time dependence which at present is recommended as a standard. In case of the fast neutron induced fission of 235U the measured decay curve of delayed neutrons shows excess of counting rate in the time interval 0.01-0.2 s as compared with the decay curve corresponding to the recommended data.

THPSC51	Ion Source Deuteron Beam Acceleration in Gas-filled Ion-optic System	ion, electron, neutron, space-charge	444
	V.I. Rashchikov MEPhI, Moscow, Russia
	Deuteron beam acceleration in ion-optic system of gas-filled neutron tubes was investigated. PIC code SUMA* used for computer simulation of ionization and knock on processes and there influence on deuteron beam parameters. When deuteron and ionized particles space charge self-field forces become the same order of magnitude as external one, virtual cathode may occurs. It is happens because of injected from ion source deuterons cannot overcome their own space charge potential wall and move in transverse direction. However, electrons, produced by ionization, are trapped within the deuteron beam space charge potential wall and decrease it significantly. Thus, space charge neutralization of deuteron beams by electrons, may considerably increase target current and, as a result, output neutron flow. Moreover, own longitudinal electric field rise near the target leads to reduction of accelerating electrode – target potential wall, which was made to prevent knock on emission from the target. As a result, additional knocked on electrons may appear in the region and should be taken into account. The data obtained were compared with experimental results. * A.N. Didenko, V.I.

THPSC52	Dynamics of Plasma-Beam Formations in the Acceleration Gap of the Pulse Neutron Generator-based Vacuum Neutron Tube	plasma, neutron, ion, vacuum	447
	S. Sergey, S. Maslennikov, E. Shkolnikov National Research Nuclear University (MEPhI), Moscow, Russia A. Agafonov LPI RAS, Moscow, Russia
	The analysis of dynamics of plasma flows containing deuterium, zirconium ions, and electrons in acceleration gap of the pulsed neutron generator vacuum neutron tube* is presented in the paper. The investigations have been undertaken with the use of code KARAT** for the two-dimensional time-dependant regime. The limiting currents of each component for the real geometry of acceleration gap have been determined. The differences between the values of these currents and those determined with the use of the Child-Langmuir equation have been demonstrated. The analysis of dynamics of plasma emitter in the gap has been performed by the example of accelerating voltage of 120 kV and pulse duration of 1.2 mks. It has been shown that the value of the current incoming in the gap from the ions source can differ strongly from the current value at the target. For increasing of this value the partitioning of acceleration gap with the use of conductive grid which is transparent for beam and has several geometric configurations has been proposed. The ring configuration of the emitter has been considered for the same purposes. The calculations have shown that the combination of these two methods described above can allow transporting deuterons current from the anode grid to the target without losses. * E.P.Bogolubov, V.I.Ryzhkov, D.I.Yurkov.

On the tandem accelerator with vacuum insulation in a steady long mode it was obtained 1.6 mA current of protons with 2 MeV energy. It was studied the one of the possible reasons of current limitation – the appearance of accompanying charged particles during acceleration of the ion beam. The paper presents and discusses the results of the accompanying beam measurement using a special detector. The detector registered an opposite positive current in the range of 80-170 mkA, which is directly dependent on vacuum conditions in the accelerator. Also it was measured the dependence of the dose rate on the total current in the accelerating gap. These measurements confirmed that injected H⁻ beam ionizes residual and stripping gas mainly in the area before the first electrode and two proposals were made to minimize the accompanying current.

The paper presents and discusses the project of modified gas stripping target. The idea of the target modification is the following. Inside the high-voltage electrode just behind inlet aperture it is proposed to apply 1 T transverse magnetic field using a two-pole permanent magnets. Similar magnets at the exit of the stripping target return proton beam back to the axis of accelerator channel. In this geometry not only significant suppression of ion penetration of the stripping gas into the accelerating channel can be achieved, but also a significant improvement of vacuum conditions in the accelerating channel and reduction of the ultraviolet radiation from the plasma in the stripping target. It is enough to shift the stripping target to a distance greater than the aperture (20 mm) in the high-voltage electrode and to implement a differential gas pumping. The paper presents results of trajectory calculation of the injected ion beam in Comsol Multiphysics. The geometry of the magnetic system and the system of differential gas pumping using turbomolecular pump installed inside the high-voltage electrode are presented.

In the present work the installation created on the basis of the accelerator EG-1 (IPPE) for the experimental studies of the time dependence of delayed neutron activity from neutron induced fission of 235U is described. Measurements were carried out with neutron beam generated with the help of the 7Li(p, n) reaction. The lower limit of the investigated time range was governed by the proton beam switching system that was 20 ms. It was shown that the temporary characteristics of delayed neutrons from the fission of 235U by epithermal neutrons is consistent with the time dependence which at present is recommended as a standard. In case of the fast neutron induced fission of 235U the measured decay curve of delayed neutrons shows excess of counting rate in the time interval 0.01-0.2 s as compared with the decay curve corresponding to the recommended data.

Ion Source Deuteron Beam Acceleration in Gas-filled Ion-optic System

V.I. Rashchikov
MEPhI, Moscow, Russia

Deuteron beam acceleration in ion-optic system of gas-filled neutron tubes was investigated. PIC code SUMA* used for computer simulation of ionization and knock on processes and there influence on deuteron beam parameters. When deuteron and ionized particles space charge self-field forces become the same order of magnitude as external one, virtual cathode may occurs. It is happens because of injected from ion source deuterons cannot overcome their own space charge potential wall and move in transverse direction. However, electrons, produced by ionization, are trapped within the deuteron beam space charge potential wall and decrease it significantly. Thus, space charge neutralization of deuteron beams by electrons, may considerably increase target current and, as a result, output neutron flow. Moreover, own longitudinal electric field rise near the target leads to reduction of accelerating electrode – target potential wall, which was made to prevent knock on emission from the target. As a result, additional knocked on electrons may appear in the region and should be taken into account. The data obtained were compared with experimental results.

The analysis of dynamics of plasma flows containing deuterium, zirconium ions, and electrons in acceleration gap of the pulsed neutron generator vacuum neutron tube* is presented in the paper. The investigations have been undertaken with the use of code KARAT** for the two-dimensional time-dependant regime. The limiting currents of each component for the real geometry of acceleration gap have been determined. The differences between the values of these currents and those determined with the use of the Child-Langmuir equation have been demonstrated. The analysis of dynamics of plasma emitter in the gap has been performed by the example of accelerating voltage of 120 kV and pulse duration of 1.2 mks. It has been shown that the value of the current incoming in the gap from the ions source can differ strongly from the current value at the target. For increasing of this value the partitioning of acceleration gap with the use of conductive grid which is transparent for beam and has several geometric configurations has been proposed. The ring configuration of the emitter has been considered for the same purposes. The calculations have shown that the combination of these two methods described above can allow transporting deuterons current from the anode grid to the target without losses.

Designed neutron generator is designed for a neutron yield 1x10¹¹ neutrons / s in continuous mode and includes ion accelerator with an accelerating voltage, continuously adjustable in the range of 120-150 keV and a beam current of atomic deuterium ions up to 2 mA, and the target device, in which used Ti-T target different diameters. In addition to high and stable yield of neutrons in time when operating continuously generator provides pulsed mode of operation over a wide range of duration and pulse repetition rate. Pulsed neutron generator operation is performed by modulating the discharge current of the ion source. For this purpose, a unique system of power discharge, which allows for both continuous and pulse modes. In this case it is possible to produce a smooth adjustment of the pulse width of the beam current. Switch from pulse mode to DC promptly made with the remote control.
